January 2018 GitHub on analyzing the Facial Expressions. I build an in house CNN model to classify the 7 different expressions using a 55K+ image DB. I used an Nvidia GPU along with TensorFlow, Keras, and Cuda process on AWS EC2 instance along with 400 GB attached volumes. The confusion matrix showed over 99% accuracy. The misidentified classes were sadness vs fear and anger vs surprise.

September 2017 GitHub on Real Estate housing prices. For this project, I used AWS EC2 instances to Grid Search the best regressor model with the minimum median absolute percent error. The best result achieved via Gradient Boosting Regressor with 11.3 MAPE.
